High pressure drainage board is made of HDPE material. It is our company's patented product, and its compressive strength can reach 450kpa. Has a high pressure resistance and impact resistance. Can withstand long-term high pressure, the size of this product is 500 * 500 * 25 / 30mm, drainage and water storage layer. To meet the needs of different projects. The product uses a buckle link. Can be seamlessly linked.
Drainage board is made of HDPE with impact resistance and pressure resistance which can resist long-term high pressure,and will not generate deformation. The long-term pressure resistance not only can resist weight of concrete bottom plate and its load, but also can bear unav oidable outside pressure and impact force during construction, for example, vehicle, worker stepping, concrete pouring impact force,etc. It can keep bottom plate undeformed for long term, so original quantity can be kept. Application of filter layer earthwork fabric on bottom plate is to ensure drainage channel is not blocked by foreign object, for example, backfilling particle or concrete.
1、lexible transportation and simple construction.
2、Lightweight material, chemical stability, sunlight resistance, corrosion resistance, acid and alkali resistance, strong resistance. Suitable for different soil conditions.
3、Can effectively drain rainwater and reduce the pressure of waterproofing.
4、The construction is simple and requires no equipment. The overlapping is convenient to form a whole, and the drainage effect is good.
